Problems solved by technology
[0004] Among them, the electro-acoustic conversion module uses the principle of vibration to send out sound signals, and the electro-acoustic conversion module is generally directly fixed on the hearing aid shell. Therefore, the hearing aid is easy to generate vibration while converting the sound, and the sound feedback effect generated by the vibration will affect or even cancel it. Part of the human ear receives the sound signal output by the hearing aid, which reduces the sound output power of the hearing aid, increases the power consumption of the hearing aid, and reduces the battery life of the product

The invention discloses a high-power high-performance acoustoelectric conversion module with a simple design, a high-power hearing aid module and an ear-back hearing aid. The high-performance acoustoelectric conversion module comprises a sound production piece used for producing sound signals and an output piece used for outputting the sound signals to the outside, and further comprises a connecting hose, and the output end of the sound production piece is communicated with the input end of the output piece through the connecting hose. The invention discloses a high-performance acoustoelectricconversion module. The high-performance acoustoelectric conversion module is connected to the output end of the sounding piece and the input end of the output piece through the connecting pipe; the vibration transmitted to the output part when the sound production part works is reduced, so that the resonance of equipment or an equipment shell is greatly reduced or even eliminated, the sound feedback effect generated when the sound production part works is reduced or even eliminated, the output power of the high-performance acoustic-electric conversion module is greatly improved, and the energy consumption of a product is reduced.
Description
technical field [0001] The application relates to a high-performance acoustic-electric conversion module, a high-power hearing aid module and a behind-the-ear hearing aid. Background technique [0002] A hearing aid is a device that helps the hearing-impaired to improve their hearing impairment. It generally works by receiving external sound, and then processing the sound to effectively transmit the sound to the human ear. [0003] Hearing aids in the prior art are generally equipped with an electro-acoustic conversion module. The control circuit board in the hearing aid generates a corresponding electrical signal after receiving external sound, and then the hearing aid converts the electrical signal into a sound signal through the electro-acoustic conversion module, and then Then it is directly or indirectly output to the human ear through the sound pipe, so as to realize the conversion of the hearing aid to the sound. [0004] Among them, the electro-acoustic conversion m...
